[Prior Art] Far infrared rays in the invisible region with particularly long wavelengths, that is, far infrared rays, have a high degree of heat absorption into the human body, promote blood circulation,
It has an excellent thermal effect, such as buffering various types of muscle fatigue. Focusing on this point, the present application is based on a futon that has a unique three-layer structure and is equipped with a far-infrared heating element. (Utility Model Application No. 61-141225), and its structure is as shown in the cross-sectional view in Figure 3, with a bottom layer made of a flat plate-shaped synthetic resin foam material and having an elastic restoring force. 3′
and an intermediate layer 4' which is made of a synthetic resin foam material and has a wavy concave part 4a' and a convex part 4b' formed on the upper surface thereof, which are continuous approximately parallel to the width direction of the futon, and which has resistance against compressive load loading. Many mountain-shaped protrusions 5
a' and an upper layer 5' made of a synthetic resin foam material and having an elastic restoring force and having a plurality of inverted mountain-shaped recesses 5b' formed on the upper surface, and A plurality of substantially rectangular sheet heating elements 7' that emit far infrared rays are disposed on the upper surface so that the longitudinal direction is substantially parallel to the width direction of the futon and at positions corresponding to the recesses 4b' of the intermediate layer corrugated portion. This is a far-infrared radiation three-layer futon 1', characterized in that the three-layer structure and the heating element are covered with an exterior geodesic 11'.

[Problems to be solved by the invention] In the conventional far-infrared emitting three-layer futon 1' described above, the substantially rectangular planar heating element 7' is located on the upper surface of the upper layer 5' and on the exterior geodetic surface. 11', when the user lies on his or her back on the far-infrared emitting three-layer futon 1', the user senses the presence of the planar heating element 7' and feels an odd sensation in that area. It was hot.

In addition, in the conventional futon 1', a significant external force is applied to the upper side of the futon 1', such as when a foot strongly steps on the top surface of the sheet heating element 7' or when another heavy object is temporarily placed. Folding may cause the sheet heating element 7' to be deformed or damaged by bending, leaving some problems in terms of long-term durability of the sheet heating element 7'.

Furthermore, in the conventional futon 1', there was a problem with air permeability, and no provision was made to quickly transfer the heat from the planar heating element 7' to the futon 1'.

The present invention was made to solve the problems of the conventional far-infrared ray emitting three-layer futon described above, and utilizes the shape of the constituent members of the three-layer futon, which has an acupressure treatment effect and a chiropractic treatment effect. Without sacrificing elasticity or breathability, strip-shaped planar heating elements are installed to provide suitable thermal and heating effects, and provide quick in-floor heating without any change in the user's sensation. The object of the present invention is to provide a far-infrared ray-emitting three-layer futon that can be used as a heating element and has long-term durability as a sheet heating element.

[Means for Solving the Problems] The above-mentioned problems are caused by the bottom layer having elastic restoring force made of a flat synthetic resin foam material, and the continuous wavy uneven portions extending approximately parallel to the width direction of the futon. An intermediate layer made of a synthetic resin foam molded on the top surface and having resistance to compressive loads, and a synthetic resin foam material with a large number of mountain-shaped convex parts and a large number of reverse mountain-shaped concave parts formed on the top surface. For a futon made of a three-layer structure in which an upper layer is laminated and has an elastic restoring force, the longitudinal direction of the upper surface of the intermediate layer is made to be approximately parallel to the width direction of the futon, and the concave portion of the wavy portion of the intermediate layer is formed. A plurality of substantially strip-shaped planar heating elements that emit far infrared rays are disposed at corresponding positions, and a support for supporting the planar heating elements is interposed in the intermediate layer recess, and the planar heating elements The present invention is solved by a far-infrared ray emitting three-layer futon, characterized in that the upper layer located on the top of the futon is provided with a plurality of ventilation holes.

FIG. 2 is a partially enlarged sectional view of an embodiment of the present invention. The three-layer structure 2 includes a bottom layer 3 made of a flat plate-shaped synthetic resin foam material such as polyurethane foam, which has an elastic restoring force and has the purpose of absorbing vibrations from the outside world that disturb sleep, and a bottom layer 3 that has the width of the futon. The intermediate layer 4 is made of a synthetic resin foam material such as foamed polyethylene, and has a wavy portion in which convex portions 4a and concave portions 4b are repeated and continuous substantially parallel to the direction, and has resistance to compressive loads, and the upper surface is Many mountain-shaped protrusions 5
It is a three-layer structure in which an upper layer 5 having an elastic restoring force and made of a synthetic resin foam material such as polyurethane foam and having a large number of inverted mountain-shaped recesses 5b are laminated.

The middle layer 4 is a slightly rigid wavy body that firmly supports the weight of the supine human body M, allowing the correct sleeping posture without causing heavy parts such as the buttocks and back to sink excessively. It has the effect of correcting spinal distortions caused by unreasonable posture during the day (manipulative effect) and relieving or curing disorders such as lower back pain. Also, the upper layer 5
has breathability and the intermediate layer 4 (especially the convex portion 4a)
In addition to softening the weight support by the upper layer 5, an effect of pressing the surface of the human skin by the many protrusions 5a of the upper layer 5 (acupressure effect) can be obtained.

The numeral 6 is a net body which prevents deterioration of the weight support strength of the three-layer structure 2 and contributes to long-term stable use.

On the upper surface of the intermediate layer 4, a plurality of substantially strip-shaped heating elements 7 that emit far infrared rays, the longitudinal direction of which is approximately parallel to the width direction of the futon 1, are placed above the recess 4b of the intermediate layer 4. A plurality of them are appropriately placed at corresponding positions, for example, at the feet, at the waist, at the shoulders, or at other parts where far-infrared rays can be effectively irradiated.

Further, a planar heating element 7 is provided in the recess 4b of the intermediate layer 4.
A support body 8 is interposed to support the. Support 8
is made of, for example, a slightly hard material such as foamed polyurethane, and is heat resistant and prevents extreme deformation or bending damage of the planar heating element 7 due to external force applied from above. In order to quickly transmit the heat generated by the planar heating element 7 to the upper surface of the futon 1, a plurality of ventilation holes 5c are provided in the upper layer 5 located above the planar heating element 7.

In addition, the sheet heating element 7 is disposed inside the three-layer structure 2, and the area around the sheet heating element 7 has heat retention properties, so it can generate heat efficiently with small electric power. be able to. In addition, the planar heating element 7 has a self-temperature regulating property (as the heating element rises to a certain temperature, the electrical resistance value increases, the current value decreases, and the temperature is maintained at a constant temperature). The power consumption of the sheet heating element 7 can be further reduced by selecting a suitable material, or by attaching aluminum foil or an aluminum vapor-deposited resin sheet to the lower surface of the sheet heating element 7 to reflect far infrared rays upward. It is possible.

In addition, an ion battery band 9 made of a flexible woven fabric coated with a carbon-containing good conductor is placed on the top surface of the three-layer structure 2 at the foot of the body, for example, to transfer high-voltage negative charges to ions. When applied to the electric bed band 9, the human body can be prevented from becoming acidic, and negative potential therapy can be performed during sleep, which has a therapeutic effect on back pain, stiff shoulders, insomnia, etc. The ion battery band 9 is, for example, as shown in FIG. 2, sewn onto the upper surface of a package 10 made of woven fabric or the like.

The above-mentioned sheet heating element 7 and ion electric bed band 9 include:
Control power is supplied via a connection cord 13, a connection connector 14, and a wiring cord 15 from a control device 12 that includes a power supply circuit timer circuit, a negative potential low generation circuit, and the like.

lies on its back, connects the connector 14, and connects the control device 1.
When the power is turned on and the desired operation is started, the planar heating element 7 is energized and irradiates the human body M with far infrared rays, producing a thermal effect and a heating effect.Furthermore, the unique structure of the three-layer structure 2 allows for shiatsu pressure. Effects, chiropractic effects, etc. are given to the human body M.

The planar heating element 7 is disposed on the upper surface of the intermediate layer and at a position corresponding to the recess 4b of the intermediate layer, and the upper layer 5 is laminated on the planar heating element 7. For the supine person M lying on his back, the existence of the sheet heating element 7 cannot be sensed, and a good feeling equivalent to that of a three-layer futon without the sheet heating element 7 can be obtained. It is.

Furthermore, in the present invention, the heat generated by the sheet heating element 7 is quickly transmitted to the human body due to the ventilation hole 5c in the upper part of the sheet heating element 7.
Since the support body 8 is interposed on the lower surface of the heating element 7, the sheet heating element 7 can sufficiently withstand external force from above.

As described above, according to the far-infrared ray emitting three-layer futon according to the present invention, it is possible to quickly obtain a heating effect in the floor with a small amount of electric power without sacrificing appropriate elasticity or breathability, and to radiate far-infrared rays to the human body. By irradiating it, you can get a thermal effect that promotes blood circulation and eliminates various types of muscle fatigue, as well as acupressure effects, chiropractic effects, etc., and the synergistic effect of these individual effects or the superimposition of two or more effects is even more effective. It can eliminate the fatigue of the day during sleep, cure diseased areas, and create a healthy body.
